Abstract

A time code generator having a time code generating circuit for generating a first time code signal in response to a vertical synchronizing signal, a memory for storing a second time code signal reproduced from a VTR, a circuit for comparing the first time code signal with the second time code signal to produce an inconformity signal, a counter for counting the inconformity signal and a circuit for loading the second time code signal to the time code generating circuit according to an output of the counter.
